Description
Physcion is a ROTICHROM® HPLC reference substance for analytical and research use, identified by CAS number 521-61-9 and empirical formula C₁₆H₁₂O₅. Its molar mass is 284,27 g/mol, supporting accurate preparation of standards and calibration solutions in chromatographic workflows. Supplied in a 20 mg plastic pack, the material suits laboratories that need defined quantities of plant-derived anthraquinone markers for method development, system suitability checks, and qualitative or quantitative HPLC work. Physcion is widely applied in phytochemical profiling, natural-product research, and quality-control studies where a reliable chromatographic reference is required. The ROTICHROM® HPLC grade from manufacturer Carl ROTH is intended for controlled laboratory environments that demand consistent identity and handling characteristics. The compact unit quantity helps conserve material across multiple analytical runs while remaining practical for routine bench use. This preparation integrates readily into standard sample-preparation and HPLC protocols used in chemical, pharmaceutical, and life-science laboratories working with secondary plant metabolites.

Questions about Physcion, ROTICHROM® HPLC, 20 mg, plastic
What is this article?
Physcion, ROTICHROM® HPLC, 20 mg, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Lab chemicals.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
